Answer :
Answer: You need to stack 6 blocks to build the block tower.
Step-by-step explanation:
Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).
Mathematically speaking:
7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes
